Scientists have linked portable computers and male infertility
BUSINESSMEN and teenage boys could be risking their fertility by using laptop computers, research suggests.
The combination of heat generated by the computers and the posture needed to balance the equipment on the lap leads to raised temperatures around the scrotum, a study has found. Past research shows that higher scrotal temperatures can damage sperm and affect fertility. And the introduction of new technology such as Bluetooth and infrared connections ? which provide wireless links to the internet ? has resulted in a growing number of men using the machines on their thighs rather than at a desk.
